I have only positive things to say. Greg is professional, patient, respectful, and accommodating. I enjoyed how he let me design the ring I imagined, while providing his expert opinions/advice throughout. The entire process from start to finish was seamless, and I never felt pressured. Most importantly, the engagement ring turned out beautiful! I will definitely be recommending Greg to all my friends.

How do I even begin to tell you how great my experience was with Jacob Mercari. I was impressed with every step of the process, from the initial consultation, all the advice of sizing and design and their honesty and pricing - it was absolutely top notch.

Gregory helped my fiance and me design my engagement ring. We came to him with a center diamond that my fiance had already purchased and he was able to understand our vision, add the additional side diamonds to compliment our center diamond and produce an absolutely stunning ring with which we are both so pleased. He is also very trustworthy and honest, both important qualities to have when handing over an expensive diamond to a complete stranger. We'll definitely be back to him soon for our wedding rings as we enjoyed the experience the first time.

Engagement Ring Store Toronto

We like to rest easy at night, knowing we have made beautiful jewellery manufactured from environmentally sustainable materials to the finest quality standards. Our philosophy is to treat customers like family.

We insist on only working with industry partners who are hard-working, trustworthy, and subscribe to the same values of promoting environmental sustainability and responsible practices. We proudly work with recycled gold and platinum and offer ethically sourced earth-mined and lab-grown diamonds.

We work with the finest artisans, using only the highest-quality alloys and materials. Our jewellery is custom-made with precision and focus. We carefully review each piece before we present it to our customers.

Our attention to detail is second to none, and every piece is rigorously and thoroughly hand-inspected before delivery. You’ll enjoy the peace of mind of knowing each diamond has been strictly graded and expertly cut.

We go well beyond the 4 C’s – carat, colour, clarity, and cut – delving into the crystal’s inner qualities and carefully critiquing it based on its purity and various colourations – to ensure that we’ll never deliver a product that is anything less than perfect.

Our partnership with you doesn’t end once we’ve delivered the perfect engagement ring – it’s just the beginning. We provide a full range of services post-delivery to ensure you maximize your investment and fulfill your dreams.

Our free aftercare services include ring sizing, inspection, and diamond or gemstone tightening to ensure a magical fit. We’ll clean your ring for the life of the ring and will be delighted to polish it for you before the wedding day.

Our mission is to consult with, advise, and educate you in a relaxed, private, and friendly environment. There are no commissioned salespeople with Jacob Mercari, just passionate jewellery design experts committed to helping you fulfill your dreams. You will never feel pressured in any way.

We make our jewellery ourselves. Complete control over manufacturing lets us keep our costs down and our quality exceptionally high.
We work directly with licensed diamond manufacturers and growers to provide the most brilliant diamonds at the sharpest possible prices. With two generations of experience in the business, we know what to look for and how to source the best products at a fair and reasonable cost.

Our industry partners are carefully screened and conform to the highest ethical standards. Our partners are regularly audited for supply chain custody, ethics, and safe working conditions.

FAQ

Yes. It is best to book an appointment with us to ensure you are given the necessary time and attention for your one-on-one personal visit. Please contact us to start the booking process.

Our first meeting will generally range from thirty minutes to one hour. We give you as much time as you need. We want to know you and help educate you regarding all the various custom design options. We aim to share our knowledge with you so you have a clear and vivid idea of what you want.  

Our core philosophy is to provide the best customer experience possible. So, in this vane, we start by learning what our customers are looking for and discuss any ideas or requirements they may have. We will then take our time to go over all the necessary information. We do not rush our customers, so you are free to take your time to decide or think about what we have discussed and contact us with any further questions. Follow-up meetings are welcomed and encouraged. The first meeting is the start of our partnership. 

We work with our customers to find the perfect design and gems needed for the project. After completing this, we send an invoice with all the details and diamond certificate numbers listed for reference and transparency. A small deposit is taken, with the remaining due at completion.

The next phase is the computer CAD design, where we work with you to ensure the design comes out exactly as you want. You can make as many changes or edits as you wish.

After the design is complete and you have given the approval to continue, we will start the manufacturing by printing the design in a 3D wax resin material, casting, setting and polishing. After this, we do a final inspection and send the piece for an independent appraisal (included at no additional charge).

We will contact you when the piece is ready for review and schedule a time to meet and pick it up at a convenient time.

Throughout the process, customers are encouraged to check in and see how things are going if they are curious or would like an update. We value this continuous communication. Customers frequently comment, at the time of pickup, how easy the process is, how comfortable they feel and how fun buying an engagement ring can be!

We believe in allowing our customers to choose between earth-mined, natural diamond or lab grown diamondsWe carry both types of diamonds in stock to view in person. Deciding between mined and lab-grown diamonds is a personal choice. We aim to ensure you have all the information available to make an educated decision.

Jacob Mercari can custom-make almost any type of jewellery

Our specialty is custom engagement rings, but we frequently produce pendants, diamond studs, earrings, wedding bands, eternity bands, and many others. All our pieces are made locally in Toronto, Canada. We work in many metal alloys, such as gold (white, rose or yellow) and platinum.

We offer a diverse range of engagement rings, including the classic solitaire, elegant hidden halo, timeless three-stone, and enchanting vintage designs.

To find the correct ring size, we offer complimentary sizing at our store in Toronto. Remember, periodic resizing may be necessary due to changes in finger size over time. Fingers will swell and contract based on factors such as weather, exertion, diet, injury, etc. The key is to find a size where the ring slips onto the finger quite easily but has some resistance when you take it off. If redness or swelling occurs, the ring is too tight. The ring is too loose if it easily falls off the finger with little or no resistance.

Regular care is essential to keep your engagement ring looking its best. We recommend cleaning it with a gentle jewelry cleaner and a soft brush as often as you like. We recommend visiting us once a year to have the ring professionally cleaned and checked.

Yes, we can add a personal touch to your engagement ring. Our skilled jewellers can engrave initials, dates, or particular messages on the inside or outside of the ring.
